Seems like a stupid question, but I do a lot of stupid stuff. :)

getting ready to paint the engine and tid bits. The block had been dipped and primered at the machine shop. Tid bits like the pulleys, water pump, etc have yet to be media blasted.

My main question is can you use a normal urethane to paint the block or will it bake off? Looking to go with the ever popular Merc blue which I believe can be found in quarts these days. I know dupli color has a Dodge color that’s pretty darn close.

Is it fine to paint aluminum cylinder heads? I just don’t see it often.

Thanks!

I primed my heads and intake with zinc chromate and then painted to match the rest of the engine. I used header paint on the exhaust ports because the paint cooked off there on my last engine. Of course my engine is all black and it will be kind of hard for you to find a blue header paint. I’m not sure how it will all work out over time yet but the zinc primer is great.

Thanks, guys! These were the exact answers that I was looking for. :thumbup

I did mine garage. Used an actual spray gun from harbor freight luckily engines hide imperfections. Lol. Used an epoxy primer and painted with an HOK color I really liked then used an imron clear.

That DP that Glass Dave is talking about is the sh!t. We use it on our hot rods.

X2.... never any issues using single stage. Lots use rattle can heat paint but not necessary and doesn't leave as nice of finish. Like dave said the epoxy primer either way.

I played with the old 81 b8110a with decent results but had to mix in more silver. Gonna have to try the Chrysler sometime. Glad you mentioned that.

I went with the 5357. Pretty stoked with it.

I should add that painting air gaps suck, lol. I had to grab a paint brush to smoosh the paint in some areas and try to fog over it to smooth it out.
